Title: Improvements in or relating to flat knitting machines
IPC: D04B15/64
Filed: 1934-07-06
Abstract: 427,522. Flat knitting - machines. STOLL, H., and STOLL, R., (trading as REUTLINGER STRICKMASCHINENFABRIK H. STOLL & CO.), Reutlingen, Wurtemberg, Germany. July 6, 1934, No. 19907. Convention date, July 8, 1933. [Class 74 (ii)] A flat knitting-frame having an adjustable stroke is characterized by cam plates grouped in casings adapted to slide in the longitudinal direction of the frame, and set by pattern mechanism through draw-bars passing longitudinally through the frame, the reversings of locks, thread - guide changes, &c., being effected by sliders and the like independently of the reversal of the carriage. Cam plates 39 ... 44, and 39<1> ... 44<1>, one or both of which may be slidably mounted, effect the change of thread-guide, each corresponding pair of cams (e.g. 39, 391) being actuated by pattern mechanism 27 through chains 45<a> and one of drawbars 33... 38 (e.g. 33). Two other groups of cam plates 56, 57, reverse the cams, and are likewise actuated by pattern mechanism 27 through chains 45 and drawbars 55. Adjustable stops 13, 14 reverse the carriage 11 through reversing lever 12 and gear 10. Assuming the carriage to be travelling in the direction of the arrow a striker 23 encounters, first a member 191 of a rocking lever 19, which gives way to the left (Fig. 3), and then the member 18<1> of a rocking lever 18. This latter rocks a shaft 22, and so, through lever 24, and rods 25, 26, actuates a cam member 31, thus releasing a driver 29, which couples a worm wheel 28 fixed to the drive, to the driving shaft 72 of the pattern mechanism. This shaft makes one revolution and sets the various cam plates. The carriage 11 continues to travel in the same direction until the lever 12 strikes the stop 14, when the carriage is reversed. Axial movement of the drawbars adjusts the cam plates by pins moving in oblique guide slots (e.g. 76). Cam sliders 60 disposed perpendicular to the direction of movement of the carriage, set cam members 79 through pins 78, provided with noses 77. The slidable cam plates can be coupled at convenient points with their drawbars by means of notches and latch levers, or pins 67. The drawbars are so disposed that the carriage may be taken out at any convenient point. As shown, the rocking lever 18 is connected by a bow 17 to the stop 14, which is, in turn, coupled to the cams 39<1> ... 44<1>.

Title: Improvements in or relating to processes for the continuous zone-refining of materials
IPC: C30B13/00
Filed: 1958-06-24
Abstract: The ingredients of a material containing at least two ingredients at least one of which has a segregation coefficient other than unity, are redistributed by passing a series of molten zones 6 and 7 (Fig. 1A) from left to right through the material 5 in a container 1, removing material at ports 2 and 3 each time the material adjacent the ports 2 and 3 is molten, and adding material at an inlet 4 at a higher elevation than the ports 2 and 3 so that the upper surface of the material 5 is inclined from the inlet 4 to the ports 2 and 3. When the minor ingredient of a two-ingredient mixture has a distribution coefficient less than one, material removed at port 2 contains less of the minor ingredient and material removed at port 3 contains more than in the original material.  Optionally, the bottom of the container may have inclines parallel to the surfaces of the material, and there may be <PICT:0840144/III/1> <PICT:0840144/III/2> <PICT:0840144/III/3> vertical partitions extending a short distance below the surface of the material to prevent overflow from the molten zones.  When the material contains two minor ingredients, one having a distribution coefficient k less than one and the other k greater than one, it is treated in apparatus as above but having a vertical baffle 63 as shown in plan in Fig. 5A.  The material is introduced at 61 and the surfaces are inclined towards ends 66 and 67.  Molten zones such as 64 and 65 are passed from left to right and material withdrawn at 66 is enriched in the minor ingredient having k greater than one, and material withdrawn at 67 is enriched in the minor ingredient having k less than one.  Material not withdrawn at 66 and 67 flows round the ends of baffle 63 towards a port 68 lower than the ports at 66 and 67 as the molten zones pass from left to right, and material reduced in both minor ingredients is removed at 68.  This process may be repeated using apparatus in cascade as shown in Fig. 8.  In a further modification material containing two minor ingredients is treated as above in apparatus shown in plan in Fig. 10A having a baffle 120, the material entering at F and being removed at 123, 124 and 125 as molten zones are passed from left to right. This may be repeated using apparatus in cascade as shown in Fig. 11A. Specifications 769,673, 786,170 and 786,171 are referred to.
